To all whom it may concern.'

Be it known that l., HELMOTH M. lini- DECKER, a citizen of the United States, residing at lNaco, in the county of Mel ennan and State of Texas, have invented a new and nseful Vater-Gage, of which the following` is a specification.

This invention relates to water gages for ascertaining the height of water in a steam boiler and more particularly to gages that are normally held closed by the weight of the operating handle and has for its object the provision of a gage that is simple in construction, with few parts and that may be manufactured with a minimum amoinlt of skilled labor.` another object is novel means of assembling the valve whereby the same may be readily taken apart for repairs without the use of tools and a further object is a novel form of valve seat and means M for retaining the same in place.

l/Vith these and other objects in view as will appear as the description proceeds the invention resides in the novel combination and arrangement of parts, more particularly pointed out in the appended claims.

In the drawing Figure 1 is a view in side elevation of a gage constructed in accordance with my invention Fig. 2 is a longitudinal sectional view of the same, parts being broken away;

Fig. 3 is a View in side elevation of the tired member of gage;

Fig. at is a sectional side elevation of the movable or swinging member; and

Fig. 5 is a top plan view of the device, parts being in central longitudinal section.

Referring specifically to the drawing by characters of reference, the gage comprises two parts designated by the numerals 1 and 2. The part 1 consists of a threaded tubular stem portion 3, adapted to be attached to the boiler shell and an enlarged head portion 4, having parallel opposite side faces 5, each face being provided with a circular groove 6, the outer rim of which is cnt away as shown at 7 to form an opening` te the groove, for a purpose to be presently described.

A flange 8 projects from the face 5 at its lower edge and is concentric with the groove 6. An arcuate seating face 9 is formed on the periphery of the portion 4f and is eccen:

tric to the groove 6. A small hole 10 is bored from the face 9 to communicate with the tubular portion 3.

The movable member 2 of the gage has oppositely disposed parallel cheek plates 11 each provided with an inturned segmental flange 12 adapted to seat in the groove 5, thus coacting to form a hinge for the two members. At the juncture of the cheek plates with an enlarged part of the member' 2, an arcuate wall 13 is formed which is eccentric to the flange 12 and closely approximates the arcuate face 9. A strip of lead 111 or similar soft metal is fitted between the plates 11 and against the wall 13 to form a steam tight lioint for the bore 10.

Segmental slots 15 are cnt through the plates 11, the outer edges of said slots registering with the wall 13 and are adapted to receive a portion of the edge of the strip 14, when the saine is swaged to its seat, as will presently appear.

A stem 16 is formed on the member 2 and is provided with an enlargement 17 adapted to fit a correspondingly shaped opening 18 in a weighted handle 19, the handle being split, as shown at 20, to permit the saine to spring' over the enlargement 17 and grip the stem.

By reference to Figs. 3 and l it will be seen the opening 7 and the flange 12 are approximately the same length, so that, when the member 2 is moved to the position shown in dotted lines in Fig. 1 the two parts may be separated for inspection and repair. In replacing the strip 14, which may be done while steam pressure is on the boiler, it is only necessary to place a new strip in position between the plates 11, connect the two members of the gage and proceed, with the aid of the weighted handle, to swage the strip to its seat, by forcing it against the face 13, this operation will force the soft metal of the strip to a perfect seat on the face 13 and also force a portion of the metal into the slots 15, thereby securely fastening the strip to the wall 13.

As the face 13 and closure strip 14 are eccentric to the hinge of the two members 1 and 2 the tendency of the weighted handle is to constantly exert pressure on the valve seat to keep it closed and a tight joint is always maintained.

A lip or ange 21 is formed on the niember 2 and serves to deflect the steam and water from the port l() when the valve is opened and prevent the same from scalding the hand of the operator.

Having thus described the invention what is claimed is:

l. In a device of' the class described comprising as cooperating parts; irst and second members, the' rst member having an arcuate seating face and a port opening thereon, the first member being further pro vided with a circular groove, the wall of the groove having` a cutaway portion; the second member having a closure for the portV and a cheek pla-te provided with a. segmental flange for engaging the circular groove in the irst member, the flange being of the same length as the cutaway portion of the groove to permit separation of the two parts when the flange and cutaway portion are brought into register.

2. In a device of the class described, comprising as cooperating parts; a fixed member, having a threaded tubular portion and a head portion, the head having parallel side faces and an arcuate seating face, circular grooves in the side faces, said grooves being eccentric to the seating tace and a bore eX- tending from the tubular portion to open on the seating face; a movable member comprising al head, cheek plates extending from the head and having segmental lugs engaging the grooves in the xed member, to adapt the two members for hinged movement, an arcuate wall on the head and between the cheek plates said wall being approXimately parallel with the arcuate face
